DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0014] A preferred embodiment of an electric vehicle handle collapsingdevice in the present invention, as shown FIGS. 1-4, includes a ␣-shapedfundamental base 20, a fitting fork tube 21, a combining member 22, anoperating member 23, a subordinate rod 24, a pull spring 25 and alocking device 26 combined together.

[0015] The ␣-shaped fundamental base 20 is fixedly welded at the frontend of the foot rest of an electric vehicle and provided at the oppositesides with a side plate 200 having an insert hole 201 in the center andhaving its topside formed with a curved edge 202,which is bored withplural engage notches 203.

[0016] The fitting fork tube 21 is composed of a sleeve 210 and a forktube 211. The sleeve 210 is fitted around the handle 11 and the forktube 211 is assembled with the fundamental base 20. The fork tube 211has a positioning hole 212 respectively bored at the lower oppositesides and aligned to the insert holes 201 of the side plates 200 of thefundamental base 20, a vertical slot 213 bored above each positioninghole 212, and plural upper and lower vertical sliding holes 214, 215bored at proper positions of the front and the rear side wall.

[0017] The combining member 22 is inserted through the lower oppositeends of the fork tube 211 and the two side plates 200 of the fundamentalbase 20 and has its opposite ends respectively extending out the outerwalls of the two side plates 200 of the fundamental base 20 and screwedwith a bolt 220 so as to pivotally combine the fork tube 211 togetherwith the fundamental base 20.

[0018] The operating member 23 to be assembled with the fork tube 211has an insert plate 230 respectively provided at the opposite sides tobe inserted through the upper sliding slot 214 in the front wall of thefork tube 211, and each insert plate 230 bored with an insert hole 231at the lower end. The operating member 23 has a pull plate 232 and afront plate 233 provided at the front side, and the front plate 233 torest against the front wall of the fork tube 211 is bored at a lowerportion with a central through hole 234 facing the lower sliding hole215 in the front and the rear wall of the fork tube 211.

[0019] The subordinate rod 24 is inserted through the two vertical slots213 in the opposite sides of the fork tube 211 and the two insert holes231 in the opposite sides of the operating member 23 and also engaged inthe two front engage notches 203 of the fundamental base 20. Thesubordinate rod 24 has its opposite ends respectively provided with astop member 240 to resist against the outer walls of the two side plates200 of the fundamental base 20 to avoid the subordinate rod 24 slippingoff. Further, the subordinate rod 24 is bored in the center with athrough hole 241 aligned to the through hole 234 of the front plate 233of the operating member 23 and the lower sliding slot 215 in the frontand the rear wall of the fork tube 211.

[0020] The pull spring 25 has its opposite ends respectively formed witha clasp 250 for clasping the subordinate rod 24 and the combining member22 respectively.

[0021] The locking device 26 is assembled with the operating member 23and the fork tube 211 for clamping and locking tightly the operatingmember 23. The locking device 26 is provided with a threaded rod 260having a pull lever 261 connected pivotally with the rear end of thethreaded rod 260. A tightening member 262 having a lengthwise throughhole 263 is fitted around the threaded rod 260. A ␣-shaped claspingblock 264 is clasped on the front side of the operating member 23 andbored in the front wall with an insert hole 265 matching with thethrough hole 234 of the front plate 233 of the operating member 23. Aresisting member 266 with a lengthwise insert hole 267 for the threadedrod 260 to be inserted therethrough resists against the rear wall of thefork tube 21. A spring 268 and a nut 269 are respectively fitted aroundand screwed with the end of the threaded rod 260.

[0022] In assembling, as shown in FIGS. 1-4, firstly, the two insertplates 230 of the operating member 23 are inserted in the fork tube 211respectively through the two upper sliding slots 214 of the fork tube211 and then the pull spring 25 is placed under the operating member 23and between its two insert plates 230. Next, the subordinate rod 24 isinserted through the right vertical slot 213 of the fork tube 211 andthe two insert holes 231 of the operating member 23 as well as the upperclasp 250 of the pull spring 25 and then extends out of the leftvertical slot 213 of the fork tube 211, having its opposite endsrespectively fixed with a stop member 240. Subsequently, the threadedrod 260 of the locking device 26 is inserted through the tighteningmember 262, the through hole 265 of the clasping block 264 and thethrough hole 234 of the front plate 233 of the operating member 23, andthen passes through the front lower sliding slot 215 of the fork tube211, the through hole 241 of the subordinate rod 24, the rear lowersliding hole 215 of the fork tube 211 and at length inserted through theresisting member 266 and the spring 268 to be screwed with the nut 269.Lastly, the fork tube 211 has its two positioning holes 212 respectivelyaligned to the two through holes 201 of the two side plates 200 of thefundamental base 20, and after the combining member 22 is insertedthrough foresaid positioning holes 212 and through holes 201 as well asthe lower clasp 250 of the pull spring 25, the two bolts 220 arerespectively screwed with the opposite ends of the combining member 22to combine the fork tube 211 together with the fundamental base 20, thusfinishing assembly of the handle collapsible device.

[0023] In operating and using, as shown in FIGS. 3-7, the pull lever 261of the locking device 26 is pulled upward first to let the lockingdevice 26 no longer clamp the operating member 23, and at this time thepull plate 232 of the operating member 23 can be pulled upward togetherwith the subordinate rod 24, which is moved upward and disengaged fromthe front engage notches 203 and then forced to move in the rear engagenotches 203 of the fundamental base 20 along the top curved edges 202 ofthe two side plates by a pulling force of the spring 25. Thus, thehandle 10 fitted with the sleeve 210 of the fitting fork tube 21 can becollapsed downward to diminish the dimensions of the electric vehicle 1.

[0024] As can be noted from the above description, the invention has thefollowing advantages.

[0025] 1. The handle collapsing device can be operated easily, and thehandle can be collapsed quickly, convenient for the electric vehicle tobe carried about.

[0026] 2. The dimensions of the electric vehicle can be diminished afterits handle is collapsed, economizing the space for storing the electricvehicle.
